PORTABLE AIR-s'ro mcr: TANK.

Application filed March 20, 1922. Serial No. 545,135.

T all w from it may concern Be it known that CHARLES C. CAREK, a citizenof the United States, residing at Touhy, in the county of Saunders andState of Nebraska, has invented certain. new and useful Improvements inPortable Air-Storage Tanks, of which the following is a specification.

This invention relates to improvements in portable airstorage tanks, andmore particularly to that type oftank which does not require the usualair compressor or pump for filling.

An objectof this invention is to provide a suitable portable air storagetank, which is adapted to be carried on an automobile and which will beprovided with a suitable holding means, for an explosive charge, to

be used for filling the tank to the desired pressure.

Another object of the invention is to provide a suitable portable airstorage tank, which will be provided with a suitable charge-holdingbarrel and means for firing the charge when desired.

Other objects will appear as the description proceeds. ings:

Figure 1 is a side elevation of an automobile with my improved, tank inposition thereon;

Fig. 2 is an enlarged side elevation w th a portion of the running boardwith my 1mproved tank thereon; and 1 Fig. 3 is a sectional view of thechargeholding barrelfwith charge therein.

The air storage tank 1 is preferably formed of metal and is provided atone of its ends with a pressure gauge 2 and valve 3.

Adjacent the opposite end of the tank 1 is a discharge valve 4 whichconnects with the usual air supply tube 5. On the end of the tube 5 is aunion. or connecting nipple 6 which may be attached to the tube or tireto be inflated.

Positioned at the top of the tank 1, and preferably welded therein, is acharge-holding barrel 7, the same being provided with a flange 8 on theouter side of the tank 1. The periphery of the flange 8 is preferablyscrew-threaded as at 9 to receive the locking cap 10. The locking cap 10is provided with a central bore or opening 11 in which is slidablymounted a firing pin 12. This In the accompanying drawcap 10 and is heldin outward position bymeans of the coil spring 13. A lug or washer 14 iscarried by said pin for holding the same within said locking cap.

A suitable cartridge or charge 15, is adapted to be placed in the barrel7 and to be ignited or fired by the firing pin 12.

Assuming that the tank 1 had no air therein, a cartridge or charge wouldbe inserted in the barrel 7 and the locking ca 10 screweddown tight,after which the ring pin would be struck, to fire offv the saidcartridge. The force of the explosion of the charge or cartridge wouldfill the tank to a considerable pressure, preferably to "about 300 lbs.,determined by the amount of explosive in said charge. The pressure gaugewould readily show the pressure of the air within the tank 1, so thatwhen the pressure I got down to such a low degree of usefulness, itwould be 'a simple matter to insert a new charge, and fire the same,thereby building up the pressure the desired amount.

It will be understood that this air supply tank receives all of itspressure from the charges or cartridges,.and is not dependent at allupon the customary air compressors or pumps.

Many minor changesin detail of construction maybe resorted to withoutdeparture from the spirit of the invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States is:

11 A' portable air' supply tank compristachably secured to said barrel,a firing pin slidably carried by said locking cap, and an outlet fromsaid tank adapted to be connected to a tire ortube. i

2; A portable air supply tank comprising a charge holdingbarrelextending through one wall thereof, a flange formed on the outer end ofsaid barrel, a locking cap detachably connected tosaid barrel, and aslidable firing pin resiliently mounted in said cap. y

3.
